Electric kettles have become kitchen essentials for quickly boiling water for tea, coffee, instant soups, or baby bottles—far faster and more energy-efficient than stovetops or microwaves. The Cosori Electric Kettle, No Plastic Contact With Water, Wide Mouth For Easy Cleaning, Auto Shut Off, 1.7L Tea Kettle & Hot Water Boiler, Water Heater & Teapot, Borosilicate Glass, Black, 1500W stands out in the crowded market by prioritizing purity and safety: its design ensures water never touches plastic, using borosilicate glass for the body and stainless steel for critical interior parts like the spout, filter, and inner lid.
This 1.7-liter (about 7 cups) model appeals to health-conscious users avoiding potential chemical leaching from plastic, tea and coffee enthusiasts seeking clear visibility and pure flavor, and busy households needing rapid boiling. Priced affordably (typically $25–$40), it ranks as a top Amazon bestseller and Choice in electric kettles, with over 46,000 reviews averaging 4.5 stars—praised for fast performance, elegant looks, and reliable safety features.
In this comprehensive review, we’ll explore its design, features, performance, ease of use, cleaning, pros/cons, comparisons, and value to see if this Cosori delivers on its promise of clean, quick, and stylish hot water.
Design and Build Quality
The Cosori features a striking, modern aesthetic: a crystal-clear borosilicate glass carafe paired with black accents, stainless steel elements, and a matte base. Measuring approximately 9 x 6 x 10 inches and weighing around 2.7 pounds, it’s compact yet substantial, with a sleek V-shaped spout for precise pouring (great for pour-over coffee or French press).
Borosilicate glass—known for thermal shock resistance—forms the main body, resisting cracks from temperature changes better than ordinary glass. The interior avoids plastic entirely: stainless steel lines the spout, filter (removable for descaling), and inner lid, ensuring pure-tasting water without off-flavors. A blue LED illuminates the base during boiling, creating an attractive “light show” effect visible through the glass.
The cordless 360-degree swivel base with cord storage adds convenience, while the ergonomic, cool-touch handle (with finger guard) enhances safety. Build quality impresses for the price—sturdy connections and durable materials—but the glass remains fragile if dropped or mishandled, a common note in reviews.
Features and Functionality
At its core, this is a straightforward, single-temperature kettle: fill, place on base, press the power switch, and it boils to 212°F (100°C) automatically. Key safety includes auto shut-off and boil-dry protection (Strix thermostat for precision). No variable temperature presets or keep-warm function keep it simple and reliable.
The 1500W heating element delivers quick boiling, and the wide-mouth opening (thanks to the large lid) simplifies filling and cleaning. The transparent glass lets you monitor water levels and boiling progress easily, while the stainless steel filter catches scale or debris.
Functionality focuses on purity: ideal for green tea, black tea, pour-over coffee, oatmeal, or any application where clean water matters. The no-plastic-contact claim is a major draw for users concerned about BPA or microplastics in hot water.
Performance and Results
The 1500W power shines—full 1.7L boils in 5–7 minutes (faster for partial fills, often 3–4 minutes), quieter than many competitors due to efficient heating. Users report consistent, rapid performance, with water reaching a rolling boil reliably every time.
Taste tests from reviewers confirm pure, neutral flavor—no plastic aftertaste—thanks to the glass and stainless construction. The blue LED adds visual appeal during operation, and the spout pours smoothly without dribbling. It handles daily use well for families or heavy tea/coffee drinkers.
Minor drawbacks include no insulation (water cools quickly after boiling) and potential for louder operation near the end of the cycle in some units. Durability holds for most (years of use reported), though isolated cases mention glass cracking from impacts or thermal stress.
Ease of Use and Cleaning
Operation is intuitive: one switch, clear water-level markings inside, and automatic everything. The cordless design allows easy carrying to the table or sink.
Cleaning excels with the wide mouth and removable filter—fill with vinegar/water solution, boil, rinse, and done. The glass resists staining, and the stainless parts prevent buildup. Dishwasher-safe? Not recommended for the base, but hand-washing is quick. Users love how the large opening eliminates hard-to-reach spots common in narrower kettles.
Pros and Cons
Pros:
- True no-plastic-contact design for pure taste and peace of mind.
- Fast 1500W boiling (3–7 minutes depending on fill).
- Elegant borosilicate glass with blue LED illumination.
- Wide mouth and removable filter for effortless cleaning.
- Auto shut-off, boil-dry protection, and cool-touch handle.
- Large 1.7L capacity for family or multiple cups.
- Excellent value with massive 4.5-star ratings (46,000+ reviews).
Cons:
- Glass is fragile—risk of breakage if dropped.
- No variable temperature control or keep-warm.
- Exterior can get warm during/after use.
- Single boil setting limits precision for specialty teas.
- Occasional reports of early failures (though rare).
Comparison with Competitors
Compared to basic plastic kettles (e.g., Amazon Basics), the Cosori offers superior purity and aesthetics. Against other glass models like Mueller or Secura, it edges out with the full no-plastic interior (many have plastic lids/spouts) and better spout design.
For temperature control, upgrade to Cosori’s own variable-temp model or Cuisinart CPK-17 (more features, higher price). Stainless steel options (e.g., Fellow Stagg) provide better insulation but lack visibility and cost more. The Cosori balances purity, speed, and affordability perfectly for most users.
Value for Money
At its price point, this kettle delivers exceptional bang-for-buck: premium materials, fast performance, and health-focused design rival pricier brands. High ratings and bestseller status reflect strong satisfaction—ideal for upgrading from old plastic models or gifting to tea lovers.
Conclusion
The Cosori Electric Kettle (1.7L Borosilicate Glass, Black) excels as a stylish, reliable, and health-oriented choice for daily hot water needs. Its plastic-free interior ensures clean taste, rapid 1500W boiling saves time, and easy-clean features make it practical for busy kitchens. While the glass requires careful handling and it lacks advanced controls, its performance, design, and value make it a standout bestseller. Highly recommended for anyone prioritizing pure water, quick boils, and an attractive countertop appliance. If you’re tired of plastic-tainted kettles, this Cosori could be your perfect upgrade.
